  　View Summary

  The magnetic helicities of the cycloidal ordering in EuIrGe#D3#DR, with a noncentrosymmetric tetragonal structure, have been studied by circularly polarized resonant X-ray diffraction. It is shown that the helicity of each cycloidal domain is uniquely determined and satisfies the symmetry relations of the C#D4v#DR point group of the crystal structure. The result shows that the cycloidal helicity is determined by the Dzyaloshinskii–Moriya type antisymmetric exchange interaction. The domain selection and the phase transition by the external magnetic field along [100] and [110] have also been studied. It is shown that the cycloidal plane prefers to be perpendicular to the field and the transverse conical state is realized.
